battery

Replaced to board yesterday on my demon and now the battery still shows 53% charge after charging for 9 hours. Does it usually take that long to fully charge a discharged battery or I'd my battery going bad?

Get us a pic of the Charger you are using. I would use a charger rated 3v to 5v OR plug it into your Desktop or Laptop USB port. They are rated 3v-5v depending on what is plugged in (They self adjust).

so bought a new battery, but still take freakin forever (charged overnight to only 45%) and only to 91% at best. WTH is going on?!?!? I'm using an ipad charger instead of the stock one. Did the board reset as well with no change. any help?

Well now that you got the charge higher using the Ipad charger, go back to your regular charger that came with the gun and see what happens. It should only take a hour or two using that. I have no clue what's going on to be honest. It's almost like you have a constant drain somewhere.

My creeds that ive had, i dont use fast charges, they charge quickly but seem to not hold the charge very long, typically a month and a half. If i slow charged it take about 12 hours, it would last me all season. Its the same with all rechargeables, Ni-mh, Li-pol and Li-ion all have different charge times, depending on size, but also you got to be careful of the voltage of each charger and the amps. You can damage your batteries with the wrong chargers. Just stick to charging from your PC on a slow charge. It will last you months. Very very slim chance of damaging the battery. Also these batteries you dont want to leave on a charger and forget about them. Charge them, once they hit full take it off unless you have a smart charger that knows when the battery is full and it stops charging.. Leaving the battery plugged into the gun also slowly discharges the battery over time. Same with alkalines.

do some research on differences of batteries and how to maintain a recharge.
